The color-patches of vision part, shift, and reform as I move through space in time. The present is the object of vision, and what I see before me at any given second is a full field of color patches scattered just so. The configuration will never be repeated. Living is moving; time is a live creek bearing changing lights. As I move, or as the world moves around me, the fullness of what I see shatters. “Last forever!” Who hasn’t prayed that prayer? You were lucky to get it in the first place. The present is a freely given canvas. That it is constantly being ripped apart and washed downstream goes without saying; it is a canvas, nevertheless.
—Annie Dillard, Pilgrim at Tinker Creek
